FRIEDRICH TIVICK, OF SHEBOYGAN, WISCONSIN.

COMBINED LAND-ROLLER AND CLOD-CRUSHER.

EPECIFICATION forming part. of Letters Patent No. 365,209, dated June21, 1887.

(No model.)

To all whom it may concern.-

Be it known that I, FRIEDRICH Twrcrc, of Sheboygan, in the county ofSheboygan and State of \Visconsin, have invented a new and usefulImprovement in Combined Laud-Roller and Clod'Crusher, of which thefollowing is'a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is aplanview of my combined landrollcr and clod-erusher, partsbeing broken away. Fig. 2 shows the inner side of one of the side barsof the frame. Fig. 3 is a sectional side elevation of the machine. Fig.4 is a longitudinal section of a colter-shaft and a cross-section of theshaft-bearings. Fig. 5 is a rear elevation of a central section andshowing a part of the main frame. Fig. 6 *is a sectional elevation ofoneof the colters. Fig. 7 is a sectional elevation of the mechanism forconnecting a wheel with the main frame.

The object ofthis invention is to improve the construction of thecombined land-rollers and clod-crushers for which Letters Patent No.339,601 were issued to me April 6, 1886, in such a manner as to makethem more convenient in use and more reliable in operation.

The invention consists in the construction and combination of variousparts of the machine, as will be hereinafter fully described, and thenpointed out in the claims.

A represents the main frame of the machine, to the centers of the crossbars of which is attached the tongue B. The side bars, C, of the frame Aare made of iron, have their middle parts curved downward, and haveflanges D at their ends, to receive the ends of the crossbars of thesaid frame, and flanges E at their centers, to receive the mechanism forconnecting the wheels and the eolter-shafts with the main frame, as willbe hereinafter described.

To the centers of the side bars, C, of the frame A are attached bolts F,to which are pivoted, at their angles, the elbow-levers G. To the shortarms of the elbow-levers G are attached the axles II of the wheels I,that carry the machine. The other arms of the elbowlevers Gare madelong, or have handles attaehed to them, so that they can be readilyoperated. Vith this construction, when the short arms of theelbow-levers G are in ahorizontal position and the long arms vertical,the frame A and its attachments will be lowered, and the machine willrest and be carried upon the colters, hereinafter described. Vhen thelong arms of the elbow-levers G are swung down into a horizontalposition, the short arms of the said lovers will be swung down into avertical position, the frame A and its attachments will be raised,raising the colters from the ground, and the machine will rest and becarried upon the wheels I. The outer ends of the long arms of theelbow-levers G, when in a horizontal position, rest in keepers J,attached to the frame A, and are secured in the said keepers by pins K,passed through them above the said ends.

L are circular colters, the sides of the faces of which are beveled upona curve to form ta pered edges, as shown in Figs. 1, 5, and 6. Thecolters L may be of any desired diameter from twelve to twenty-eightinches, are preferably cast hollow, (see Fig. 6,) and are placed side byside upon two shafts, M, where they are secured in place by washers Nand set-screws O, as shown in Figs. 1 and 5. The two shafts M are placedparallel with each other, and their ends are secured to the under sidesof the side bars, C, of the frame A by bearings 1?, bolted to flangesupon the said side bars in such positions that the edges of the coltersof the one shaft will be in the spaces between the edges of the coltersof the other shaft, as shown in Fig. 1. The shafts M are tubular, havetheir ends closed by plugs Q or caps, and have holes R in the sides,neartheir ends,eonnecting with annular grooves in the inner surfaces of thebearings I, so that oil poured into oil-cups S on the upper parts of thesaid bearings will flow into the interiors of the said shafts.

In the shafts M, within the hubs of the colters L, are formed holes T,through which oil can escape to lubricate the bearings of the saidcolters.

To the front and rear crossbars, both or either, of the frame A areattached bars U, in the adjacent sides of which are formed verticalgrooves V,to receive ribs IV, formed upon the outer sides of the sidebars of the vertical frames X, so that the said frames can. be moved upand down vertically.

To the lower ends of the side bars of the v by washers a and set-screwsb, as hereinbefore attached to cross-bars j.

frames X are attached perforated tubular shafts Y, provided with coltersZ, secured in place described with reference to the shafts M and coltersL. a

To supports a, attachedto the centers of the 'top bars of the frames X,are pivoted the ends of levers cl,whieh are fulerumed to standards 6,attached to the tongue B. The inner ends of the levers d engage withcatch-bars f, attached to the frame A, so that the said levers will beheld securely in place when adjusted to raise the frames Xand colters Zaway from the ground.

' g is the drivers seat, the standard h of which is attached to thetongue B.

,z' are scrapers, the engaging ends of which are so formed as to fitinto the spaces between the beveled edges of the colters, andthus.remove any soil that may have lodged in the said spaces. The shanksof the scrapers i are The forward cross bar j is secured to the bars 10,attached to the frame Aby bolts Z, which pass through short slots in thesaid bars 76, so that the said crossbar j and its scrapers can be movedforward or back to adjust the engaging ends of the said scrapers at anydesired closeness to the colters L. To the rear cross-bar j are attachedthe forward ends of the plates m, the rear ends of which are secured tothe rear cross-bar of the frame A by bolts n. The rear ends of theplates at are slotted to receive the bolts 12, so that the rearcross-bar j can be moved forward or back to adjust the engaging ends ofits scrapers to any desired closeness to the colters.

-I-Iaving thus fully described my invention, I claim as new and desireto secure by Letters Patent- 1. In a combined land roller andclodcrusher, the combination, with the middle part of the end of theframe A, of the bars U, having vertical grooves V, the sliding frame X,carrying a series of beveled-edged colters, and having tongues "Wengaging with the having outlet oil-holes T within the hubs of the saidcolters, substantially as herein shown and described, whereby thecolter-bearings can be readily oiled,as set forth.

3. In a combined land roller and clod crusher, the combination, with theframe and a series of colters having beveled'edges, of a cross-bar adjustabl y secured to the said frame, and scrapers secured to saidbar,whereby provision is made for adjusting the said .scrapers to orfrom the colters, substantially as herein shown and described.

4. In a combined land roller and clodcrusher, the combination, with theframe A and the forward series of colters, L, having beveled edges, ofthe scrapers i, the cross-bar j, carrying the said scrapers, the slottedbars lc, attached to the frame A, and the connect" ing-bolts l,substantially as herein shown and described, whereby the spaces betweenthe said edges will be kept clear ofsoil, as set forth.

5. In a combined land-roller and clodcrusher, the combination, with theframe A and the wheels I, of the side bars, 0, provided with the flangesD E and the pivot-bolts 1 the elbow-levers G, pivoted to thcsaid bolts,

and the axles I-I, attached to thelower ends of the said elbow-levers,substantially as herein shown and described;
